and its object is to remedy the the users.

an electromagnetic nature.

The electromagnetic system negligence of The means cooperate with the 6 opening of the door of the latrines and are of according to this invention comprises an electromagnet Whose movable armature is s ecured to the lever releasing the flush of water and which is switched on by means of a switch actuated by means of a door knob or the like used for opening the door. This device automatically actuates the flushing device when the user leaves the latrine, but is not action when the user enters it. The accompanying drawings brought into show various connections. Figure 6 repres ents a device for opening a door. Figure 7 shows a door'of the latrine together with means for operating the flushing device. In the drawings 1 is a staple, 2 is a lock bolt, 3 is an operating handle or knob, 1 is a stud rigidly secured to said bolt and 5 is a recess into w hich' the lock bolt may enter, formed in an insulating disk 6 on which are mounted the terminals 7 and 8 connected to the circuit of an electromagnet.

The terminal 8 carries a-spring strip 9,

whose outer end carries a contact piecelO. The terminal 7 carries a second sprlng strip 11 on whose outer end is dispo of an insulating substance, wh

sed a plate 12 ich carries on its face adjacent the contact piece 10 a second contact piece 13 connected electrically to the terminal 7 in any suitable manner, not

shoWn in the drawings, and ad apted to come in both directions. the electric fastening device upon a metallic plate, not show ings,'which is secured to the the bolt 1.

The several parts of are mounted n in the drawdoor ad acent The operation of the fastening device shown in Figures 1, 2, 3 and 4 is as follows: Figure 1 shows the devicein the closed position, and herein the stud 4 is at the exterior of the recess 5,-the strip 11 is in the inoperative position; the contact pieces 10 and 13 are separated. Figure 2 shows the said device in its opening position. By means of the knob 3, the bolt 2 is moved in its guides in the known manner; the stud d enters the recess 5 and comes into contact with the uper part of the ramp 1%, thus lowering the ramp and with it the plate 12 as wellas the contact piece 13 which now meets the contact piece 10 and thus closes the circuit of'the electromagnet.

Figure 3 shows the lock bolt in a complete, ly opened position. The stud 4: is outside of the rampl l, which is freed from its pressure and returns'together with plate 12 to the inoperative position under the action of the spring strip 11; the contact pieces 1310 are separated and the circuit of the electromagnet is again opened.

Figure 4 shows the lock bolt during its c1os ing movement. l Vhen controlled by the knob 3, said bolt leaves its recess 5. The stud 4 comes into contact with the lower part of the ramp (Fig. 1) the ramp is released and is brought, together with the plate 12 and con tact piece 13, into the inoperative position, the circuit of the electromagnet being open.

Thus the whole operation of the lock bolt has only caused a momentary closing of the circuit of the flushing electromagnet when the door is opened for the exit from the latrines.

Figure 5 shows the electromagnetic arrangement; 15 and 16 are two electromagnets having a common armature l7, pivoted at 18, and adapted to come into contact with the contact piece 19 or 20. The armature can be pressed against either of the two contact pieces by means of a spring, not shown in the drawings. The switchdevice 21 comprises a door contact, the circuit being closed when the door is opened, or inversely. The contact device 22 represents a switch disposed within the staple of the lock bolt, in such manner, that the circuit will be closed when the door is fastened and the lock bolt is entirely inserted into the staple, this contact ceasing when the lock bolt is removed from the staple.

The contact device 23 comprisesa switch controlled byan arm 24 mounted upon the armature 25 of the electromagnet 26, which, when energi iecl; sets ofi' the-flesh of water.- The electric contact is closed by the switch 23 when the electromagnet 26' is euergizec and its armature 25 is entirely withdrawn into the electromagnet The contact is opened when the electromagnet is no longer energi-zed thearmature 25 andth'e' arm-241%- sunre the inoperative position as shownin the w g f These parts form three circuits which are supplied wi-thcurrent by means of terminals 27 and 28.; The first circuit comprises the terminal 27, the pivot 18, the armature 17 in its position represented by the full lines, the

i terminal 19, the electromagnet 16, the contact 22 and the terminal'28; The second circuit comprises the terminal- 27, the pivot 18, the armature 17 in its position represente'dby dotted lines, the terminal 20, the contact ,piece 21,- the flushing electrode 26' and the terminal 28. The third circuit comprises the terminal 27, the electromagnet 1 5, the contact picce23 and the terminal 28;

A reaction spring 31' is secured at one end to the said plate and at the other end to a handle .32 whose stem 33, limited by two stops 34 and 35 is slidable in an aperture 35 formed in the cover 37 which is secured to the plate 29. Th sp'rin' 'g; strip witha contact piece 38 controlledhy the end 39 of the reaction spring 31, and also the spring strip with a contact piece 46 are secured to the plate 29, these two strips being connected to the circuit of the misting eiectromagnet'.
